I have the very same error ! (error already present before the recent update of your plugin)
“Starbox Note: No file was uploaded.
Warning: Cannot modify header information – headers already sent by (output started at /home/xxxxx/public_html/xxxxxxx.com/wp-content/plugins/starbox/themes/admin/Notices.php:9) in /home/xxxxx/public_html/xxxxxx.com/wp-includes/pluggable.php on line 1219
When I continue (hit enter to load that error-page again, I get “invalid user ID” BUT the changes are applied !
